“…3). Ca also plays a relevant role during cell division (White and Broadley, 2003) and the synthesis of cell walls (Eklund and Eliasson 1990), especially during latewood production (Lautner and Fromm, 2010;Sánchez-Salguero et al, 2019). Therefore, Ca availability may affect cambium dynamics and the rate of wood production and tracheid expansion (Fromm, 2010).…”

“…By analyzing the structure of tree rings, scientists can reconstruct past climate patterns and study the effects of environmental changes on tree growth [41]. This information can be used to better understand the ecology of the region, predict future changes, and inform conservation efforts [42].…”

A field sampling event was conducted to measure the concentrations of metals within the trunks of felled trees on a college campus east of New York City. Heavy metals, particularly chromium, were found present in the soils surrounding the sampled trees, allowing for a correlation coefficient to be calculated with soil and tree concentrations. A statistically significant Pearson correlation was found between these two concentrations among the samples. This study is aimed at providing researchers a starting point for their research a better understanding of local ecologies, prediction of future change, and dissemination of conservation efforts.

“…The use of XRF data is relatively rare in dendrochronology and has, to date, largely focused upon forensic investigation of environmental contamination (MacDonald et al 2011;Rodriguez et al 2018;Lehmann and Arruda 2019). Only very recent studies have considered its potential for climatological (Sánchez-Salguero et al 2018) or geological (Hevia et al 2018) reconstructions. Although it has been known for some time that heterogeneity within tree rings, such as the matrical differences between earlywood and latewood in Quercus spp, can affect XRF results (Smith et al 2008), we are aware of no attempt, prior to this study, to date timber based upon XRF-derived ring-width data alone.…”

The study of materials that comprise artworks significantly contributes to understanding of age and provenance. While dendrochronology is a particularly valuable and well-established technique for panel paintings comprising oak timber, conventional practices of resurfacing endgrains to reveal tree rings is becoming less acceptable because it removes material, modifying the painting. Recently, application of non-destructive X-ray fluorescence (XRF) spectroscopy to a portrait of Henry VIII held by the Art Gallery of NSW (AGNSW) revealed tree-ring boundaries in the resulting high-resolution elastic scatter XRF map. In this study, we examine the dendrochronological potential of that mapping with the aim of contributing to resolving the relation of the AGNSW portrait to similar paintings elsewhere. Examination of the timber revealed affinities with Quercus petraea (Matt.). We measured tree-ring widths along multiple paths in the XRF scatter map and crossdated the resulting 81-year XRF ring-width (XRF portrait ) series against master chronologies of English, western European, and Baltic origin. Rather than an arbitrarily defined threshold, we used a Bonferroni correction to determine a minimum significance level for crossdating. While the XRF portrait series did not crossdate with the continental European chronologies, we identified a single significant (α = 3.4 x 10 -6 ) dating position with the English chronology (1400-1480 CE). Cross-matching with site-level chronologies revealed a cluster of high t-values in central-southern England. The earliest date of felling precedes the documented date of completion for the AGNSW and two similar Tudor portraits of Henry VIII held by the National Portrait Gallery (NPG), London and one at the Society of Antiquaries, London. While, the apparent British provenance of timber used in the AGNSW portrait contrasts to Baltic origin of timbers used for the two NPG portraits and the majority of English panel paintings, it is consistent with the provenance of the timber used for the Society of Antiquaries portrait.
